The client who is experiencing an inferior wall myocardial infarction has had a drop in heart rate into the 50 to 56 beats/min range. The client is also complaining of nausea
The nurse interprets that these symptoms are because of stimulation of which cranial nerve (CN)? 1. Vagus (CN X)
2. Hypoglossal (CN XII)
3. Spinal accessory (CN XI)
4. Glossopharyngeal (CN IX)
1
Rationale: The vagus nerve is responsible for sensations in the thoracic and abdominal viscera. It is also responsible for the decrease in heart rate because approximately 75% of all parasympathetic stimulation is carried by the vagus nerve. CN IX is responsible for taste in the posterior two thirds of the tongue, pharyngeal sensation, and swallowing. CN XI is responsible for neck and shoulder movement. CN XII is responsible for tongue movement.
